Colonic anastomoses made both by a new Compression Anastomotic Device (CAD) and by a traditional stapler (Autosuture CDEEA) were evaluated in impaired anastomotic healing induced by systemic cortisone in the dog. Twenty dogs were given daily i.m. hydrocortisone (25 mg/kg) starting one month before surgery and then until sacrifice. Eight untreated dogs served as controls. Surgery consisted of colonic transection and anastomosis done with CAD-25 in half the cases and with CDEEA-25 in the remaining half. The dogs were sacrificed six and 13 days after surgery. Macroscopic assessment, bursting pressure test, and histology were performed on the anastomosis. One dog died from peritonitis due to anastomotic dehiscence. No other clinical complications were observed. Although the number of observations was too small to attain statistical significance, CAD anastomoses appeared better than stapled ones as regards peri-anastomotic adhesions, anastomotic index, and histology. This preliminary study suggests that compression is as reliable as the stapler in the construction of colon anastomosis even in such situations of delayed anastomotic healing. Further experience is required to substantiate this conclusion.
